The Map constructor takes an iterable of [key, value] pairs. Array.from
takes an iterable of elements.This asymmetry is presumably because the
Array constructor's behaviour is already defined. A hypothetical Map.from

Not quite true: Array.from,
The other motivation might be subclasses - MyArray.from creates a MyArray,
MyMap.from would create a MyMap.

Some food for thought from a non-standard use-case.
In GPSEE, we can require(module) - but we support both modules written in

the correct C API), or both. We dlload(module.so) (if present), then
interpret module.js (if
